This invention relates to scrapers and particularly to devices of this class comprising a holder in connection with which double edged blades of different contour may be 5 mounted in connection'with the holder or clamped between the jaw members thereof; and the object of the invention is to provide a tool of the class described comprising a holder of unitary construction, the blade supporting end of which is split centrally and longitudinally to form relatively flexing jaw members within and between which a blade is adapted to be securely clamped, one of the jaw members being longer than the other to provide a transverse channel at one side of the blade of the tool 5 a further object of the invention being to provide a tool of the class described employing scraper y blades having two scraper edges extended to 0 opposite sides of the blade, or one of said edges may constitute a straight edge and the other a curved or oiset edge to-compensate the tool for different uses of the tool; a still further object being to provide means or supporting the blade within and between the Jaw members and inwardly of the outerl edge thereof; and with these and other objects inview, the invention consists in a tool ofthe class and for the purpose specified, 0 which is simple in construction, efficient in use, and which is constructed ashereinaftci` described and claimed. 'i The invention is fully disclosed in the following speciiication, of which the -accom- 5 panying drawing-.forms a part, in which the separate parts ofmy improvement are designated by suitable reference 'characters in each of the views, and .in which Fig. 1 is a plan view of a tool made accordo ing to my invention, with part of the construction broken away and in section.

In carrying my invention -into effect, I o

provide a holder 10 consisting of a handle member 11 and a blade supporting body 12 at the free end of the handle member, said body being greater in width than the handle member, and said handle member being preferably provided with outwardly flaring side y walls 13 joining the body 12 in curved walls 14.- so as to provide for the proper gripping of the tool in the hand, facilitating the movement ofthe tool over a surface in the operation thereof.

The handle member 11 and body 12 are of unitary constructionand said body 12 is prosaid body into separate blade gripping jaw members. 16 and 17, the outer ends of which are rounded, the jaw 16 being longer than the jaw 17 to form a recess 18 into which vided with a-longitudinal slot 15 dividing 79 shavings are free to pass In the construc- 75 tion shown, the slot 15 extends to the point where the handle memberi'j'oins the' body 12 so that a scraper blade"`19 may be mounted in the inner portion 15a of the groove when the blade is not in use. -It will be seen that 30 the outer portion 15b of the groove is angularly disposed with respect to the inner portion, and the portions 15a and 15b intersect in transverse grooves 16a and 17 aformed in the jawmembers 16 and 17 and opening into 85 the slot 15. .These grooves are to receive the flange cutting edges at the inner sides of the blades 19 when mounted within and between -the jaw members. Other grooves 166 and 1712 are formed in the j aw members adjacent the inner end of the groove 15 or the portion 15a thereof and the jaw member 17 is provided with another oove 170 arrangedadf jacent the groove 1 a and inwardly of a clamp bolt 2O employed for securing the 9 `blade 19 within and between the jaw membody is employed as Well as a wider blade,

two or more of these bolts may be em loyed as will be apparent. The head 21 of t elbolt is arranged outwardly of the' jaw 17 in the construction shown, and the nut 22 of the bolt is disposed in a circular aperture 23 in which said nut is countersunk suiiiciently to receive the head 21 of the bolt of an adjacent scraper in packing the scrapers one upon the other for shipment. The heXagon nut 22 will have a drive it in the circular aperture 23 so as to prevent rotation of the nut therein. The scraper blade 19 shown mounted between the jaw members 16 and 17 in Fig. 2 and in detail in Fig. 3, consists of a comparatively narrow strip of metal, the side edges of which are turned, one upwardly and the other downwardly, and are curved or arc-shaped `in contour and ground or otherwise sharpened to form the scraper edges 19a of the blade.

In Fig. 4 of the drawing, I have shown at 25 another form of blade which has one off-- set scraper edge 25a similar to the edge 19a and the other edge 256 of which is straight or in alinement with the plane of the blade andground or otherwise sharpened so that the same may be used as a scraper for removing paint and other particles from window panes or other surfaces or in the removal of wall paper from walls.

In Fig. 5 of the drawin I have shown at 26 another form of blade aving at one side thereof an odset scraper edge 26a and at the other side thereof a straight, scraper edge 26?), the latter side of the blade 26 being oidset with respect to the longitudinal plane of the first named side to compensate for the ol'set arrangement of the end portions 15a and 15b of the slot 15, especially in mounting the blade 26 in the holder so Vthat the edge 26a projects beyond the jaw members in the same manner as the projecting edge19a of the blade 19 as shown in Fig. 2 of the drawing. In this use of the blade, it will be understood that the bolt 20 passes through an aperture 26o formed in the blade, and if two bolts are employed, two of the apertures 26 will be provided.

In Fig. 5 of the drawing, I have indicated the manner of mounting the blade 26 in connection with the jaw members 16 and 17 of the tool so as to project the edge 26?) thereof well beyond the jaw members 16 and 17,

thus adapting the tool for use as a wall paper remover or for similar purposes.

In Fig. 6 of thedrawing, I have shown a slight modification in the blade holder and blade, and in said ligure, 27 represents a jaw member similar to the jaw member 16, and 28 a jaw member similar to the jaw member 17 of the holder shown in Figs. 1 and 2. At 29, is shown the bolt for clampin the jaw members together, the nut end 30 o which is countersunk in a recess 31 formed in the jaw member 27, the split or clearance between the Jaw members being indicated at 32. 33 and 34 represent grooves on the inner` face of the jaws 27 and 28 similar to the grooves 16a and 17a to adapt the tool shown in Fig. 6 for use in connection with blades such as shown in the other igures of the drawing. At 35, I have shown a groove similar to the groove 170. In ractice, the jaw member 27 is pro vided ad]acent its free end with a groove 36 openinor outwardly through the inner surface thereoiD so as to receive either a transverse rib or two or more beads 37 strucl': from the central portion of a blade 38 so as to key the blade against longitudinal movement with respect to the jaw members27 and 26. In the construction shown in Fig. 6, the blade 38 has its opposite side edges ground or sharpened to form scraper edges 39 and 4.0. It will be understood, however, that one of these edges alone may be straight and the other similar to the oil'set or flanged edges as shown in the other figures. In tact, a blade such as that shown in Figs. 1, 2 and. 3 of the drawingl may be ke ed to the jaw member 27 by providing the o set rib or beads thereon. This construction eliminates the necessity of increasing the width or the blade and providing an aperture therein similar to the aperture 260 as in the construction shown in It will also be understood that while a coinparatively deep groove 36 is shown and a corresponding formed bead or rib 37, that in iact, the groove may be shallow and the rib or bead proportionately formed.

It will be understood that the several blades may be mounted within the portion 15a of the slot 15 when not in use so as to provide means for packinel and shi ping the complete device without danger o injuring the scraper edges of the blade and also without danger of injuring the parties handling the same.

It will also be understood that while I have shown certain details of construction for carrying my invention into eect, that I am not necessarily limited thereto, nor am I necessaril limited to the specific contour of the blade older herein shown and described, and various other changes in and modifications of the construction herein shown and described may be made within. the scope of y movable side jaw members, means for moving said 'aw members together to clamp a' blade wi in and between the same'and one of said jaw members bein longer than the other, and a double edged lade vadapted to be mounted and clamped between said jaw members with one of the edges projecting therebeyond, one edge of said blade being turned substantially at right angles tothe longitudinal plane of the blade, one jaw member havin a transverse groove opening into the split o said body to receive the angularly disposed ed e ofthe blade, and the split 4. in sai-d body at t e free end of the jaw meml l5 bers being disposed 'angularly with respect to the remainder thereo v 2.
